The PS Audio Stellar M700 monoblock launched at US$1,499 each (US$2,998/pair), so this US$2,199 asking price sits just above the median of US$2,047 from recent used listings, making it a fair market value rather than a bargain. It exceeds the 75th percentile of US$2,123 slightly, but not by enough to be considered ambitious given the amplifier’s strong reputation.
The Stellar M700 is well-regarded for delivering 350 watts into 8Ω with MOSFET balanced output and a Zero-loss Analog Cell input stage, offering excellent loudspeaker control via a damping factor of 1100. At this price, you’re getting a high-powered, 2Ω-stable monoblock that still carries PS Audio’s three-year warranty on new units, and if this is original-owner condition with full accessories, it’s a solid buying opportunity for those seeking serious power without stepping into boutique pricing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
PS Audio, a pioneering American hi-fi brand, traces its roots to 1973 when co-founder Paul McGowan launched the company in California alongside Stan Warren. Emerging from the analog golden age, it debuted with a standalone phono preamplifier, reflecting McGowan's early passion for vinyl playback honed through radio station connections and encounters with audio enthusiasts. The brand quickly evolved, embracing digital audio in the 1980s by releasing one of the first high-end CD players, the PS Audio CD-1, soon after Philips and Sony introduced the format.
Today, PS Audio specializes in premium electronics, including power amplifiers, preamplifiers, digital-to-analog converters (DACs), and integrated amplifiers, with a hallmark focus on power conditioning via innovative AC regenerators known as Power Plants. These devices, born from Stan Warren's mid-1980s discovery that oversized transformers enhance audio performance, remain a cornerstone. The lineup also encompasses digital lenses for refining streaming and disc playback, alongside select analog components, though it eschews speakers, headphones, turntables, or cables.
Positioned firmly in the high-end market, PS Audio commands respect among discerning audiophiles for its bold engineering and unwavering pursuit of musical purity. Celebrating 50 years in 2023, it occupies a niche as an innovator rather than a mass-market player, appealing to buyers who prioritize transformative power delivery and digital refinement in sophisticated systems.
